DISINFECTING APPARATUS.

Specification of Letters Patent.

Patented May 18, 19515.

Application filed April 23, 1912, Serial No. 692,650; Renewed October 26, 1914. Serial No. 868,740.

To all whom it may concern:

Be it known that I, JOHN R. VAN DYNE, a citizen of the United States, residing at Sedalia, in the county of Pettis and State of Missouri, have invented certain new and useful Improvements in Disinfecting Apparatus, of which the following is a specification.

This invention relates to apparatus for gradually and continuously feeding disinfecting liquid to places-where it is required.

The present invention relates particularly to apparatus of the type shown in my prior Patents No. 893,208, dated Julyi14, 1908 andNo. 931,817, dated kAugust 24, 1909.

The primary object of the invention is to provide disinfecting apparatus for use on railway trains, steamboats and the like, so designed that the disinfecting liquid will be fed only when the conveyance is in motion, thereby preventing the waste of disinfectant when it is notneeded, as, for example, when a car is standing idle upon a siding.

l/,V ith the above and other objectsin view, the invention consists in the construction and arrangement of 'parts hereinafter described and illustrated in the accompanying drawings, in which,

Figure 1 is a central vertical section through my improved apparatus; Fig. 2 is an invertedplan view thereof, parts being in section, on the line 2-2 of Fig. l; and, Fig. 3 is a vertical section on the line 3-3 of Fig. 2. n"

Referring to the drawings in detail, my improved apparatus comprises a kcontainer which is madeup yof two sections 1 and 7 detachably connected, and held together by the frictional engagement of the upper part of the section 7 with the flange 1a at the lower part of the section 1. A screw top 2 is provided through which the apparatus may be lilled with a suitable disinfecting liquid. A transverse partition 3 divides the container into upper and lower compartments, and depending centrally fromk this partition isa concentrically disposed cylindrical extension 4 which lies within the lower section or cup 7. The extension 4 is provided with a bottom 5 having a central opening constituting a valve seat, such opening being preferably protected by a wire gauze screen 8, as in my prior Patent No. 931,817 above referred to. A conical valve 9 coperates with the above mentioned seat, and is carried by a float 10 made of the drawing.

ed from falling away by means of a yolre 11, Y

and is surrounded by a guard ring 12 of the same diameter as the extension 4.V

In' the upper `part of the cup 7 are formed a plurality of openings 7a through which disinfecting vapors may escape into the air. In order to facilitate the dissemination of such vapors a wick 6 dips into the liquid in the cup 7 and surrounds the ex: tension 4 and ring 12, as clearly shown in .Theabove described construction of ccntainer isy simple and pract1cal and obviates the necessity for inner and outer casings asV heretofore employed.

Rigidly secured tothe bottom of the `cup 7 is a tube 13 which is preferably vertically arranged and which has, atits vlower end an opening 14 to permit the entrance of liquid. Vlithin the tube 13V is adapted to telescope a tube 15, having at itsupper end an annular enlargement or shoulder 16 Vadapted to engage the upper edge yof the tube 13. Inclosed within the tube 15 is one end of a siphonV wick 17, the other endof which is usual discharge nipple 19. The tubes 13 and 18 arek rigidly united at their upper ends by the brace 20, and, as clearly shown in Fig. 2, are disposed 'in' the annular' space between the extension 4 and the walls ofthe cup 7. The tube 15 is open at its lower end but is provided with a cross bar or pin 15a which prevents the wick 17 from projecting thlrough or beyond the lower end of the tu e.

In practice the liquid level is indicated by the line w, and the length of the tube 15 is such that its lower end will lie at a point just above such liquid level, further downward movement being prevented by virtue of the engagement of the annular shoulder 16 with the upper edge of the tube 13, Under these conditions, when the apparatusr is at rest it will be seen that the wick 17 is out of contact with the liquid and therefore does not feed any disinfectant into the delivery tube. As soon, however, as the apparatus is Y y www ingof a conveyance, such as a railway car, such movement produces agitationof vthe liquid in the tube 13 and causes the-same to slosh upwardly so as to impregnatethe Wick v17. As long as thecar is running such agitation continuesand the continuous wettingv f tation ceases, the y,feeding ofthe disinfectant .is discontinued, forV the reason that the Wick is above the normalV liquid level in the tube.

y It Will thus be seen that by the employment A of my improved apparatus a'great saving can be effected-.in the use, of vdisinfectants Without sacrificing any of the advantages vof,

the' usual apparatus, andit vvill further be .to telescope Within saidsecond tube, a siphon observed that the feeding ofthe disinfectant p is begun and, stopped entirelyautomatically Without any attention on the part ofthe em'- ployees. n

What I claim is Y 1.- A disinfectant ycontainer comprising a cylindrical body'having atone end a cylindrical extension of less diameter than said body and at. the other end an opening through Which it may be lled, an 'open top cup of substantiallyV the same diameter as i said body Wholly inclosing said extension,

the edges of said cup and body being in frictional engagement, means controlled by the liquidr level in saidk cup for governing the flow ofliquid from said extension into the cup, wherebyA a substantially constant level inisaidcup.isfniaintained, a delivery tuloefopening throughlthe lbottom of said cup,and disposed Within theannular space between said extension and the'sides of said cup, and a Siphon wick in said tube.

2. Disinfectingl apparatus comprising a liquid container, means for maintaining a constant normal liquid level 1n said container, and a delivery Vvvick supported atV such a height that its end is just` above such normal level.

3.' Disinfecting apparatus comprising a liquid container, a delivery tube carried thereby, a siphon Wick having one end lying in said tube, a second tube also supported by said container and having an opening to admit liquid, the other end of said Wick beinginclosed in said second tube,

and means y,for limiting the extent to which Y lthe Wick may be inserted in such tube.

4. Disinfecting apparatus comprising a liquid container, a vertical delivery tubeV carried thereby, a second tube in fixed spaced relation to the first and havingan opening adjacent the bottom of said container, a`

third tube, open at both ends, and adapted` i `5. Disinfecting apparatus I comprising a liquid container, a delivery tube carried thereby, a Wick in said delivery tube, and means normally maintaining saidvviclr out of contact With the liquid When saidy container lis at rest, saidvviok being so,v positioned as to be impregnated Whenever the container is jolted. y
